This is no modern art but a carving of the Shou Shan stone. The blue, without the artistic symbolism of Western art of the sacred, the heaven, the ideal, the escape etc etc was a mean of disguise. During the cultural revolution, all objects of art and decoration were target to be destroy and its owner punished. The owner must have treasured this object, instead of destroying it like many art object at the time, a layer of blue paint was applied to escape the prying eyes of the red guards.

Odd at it is, we have kept the blue paint on, as it is part of the history of this object.
